In Long Term Evolution formula system, a medium access is controlled (Media Access Control, MAC) layer the transfer of data in logical channel is provided.When medium access control layer utilizes an entity down link control channel (Physical Downlink Control Channel, while PDCCH) indicating allocation of radio resources, the classification that maps to the temporary transient identifier of a Wi-Fi (Radio NetworkTemporary Identifier, RNTI) of entity down link control channel depends on different logical channels conventionally.For instance, the temporary transient identifier of one cellular community Wi-Fi (Cell Radio Network Temporary Identifier, C-RNTI), the temporary transient identifier of a temporary cellular community Wi-Fi (Temporary C-RNTI) and the temporary transient identifier of the cellular community of a semi-persistent scheduling Wi-Fi (Semi-PersistentScheduling C-RNTI) can be used for an exclusive control channel (Dedicated Control Channel, DCCH) and exclusive traffic passage (Dedicated Traffic Channel, DTCH).And the temporary transient identifier of an arbitrary access Wi-Fi (Radon Access Radio Network Temporary Identifier, RA-RNTI) can be used for a down link sharing channel (Downlink Share Channel, DL-SCH) (Random Access Response, RAR) message is responded in arbitrary access.As an arbitrary access (Random Access, when RA) program is triggered by an entity down link control channel order or medium access control sublaryer, networking end transmits a medium access and controls Protocol Data Unit (MAC Protocol DataUnit, MAC PDU), it carries the medium access that comprises sequential information and controls arbitrary access response (MACRAR).
Please refer to the 1st figure, the 1st figure is the schematic diagram that a known medium access is controlled Protocol Data Unit.As shown in Figure 1, medium access control Protocol Data Unit includes a medium access control gauge outfit, at least one medium access controls arbitrary access response and selectivity is filled up (optional padding) position.Medium access is controlled the beginning that gauge outfit is added on a networking grouping, makes networking grouping become the frame that can be used for network transmission.Medium access control gauge outfit is variable-length and includes at least one medium access control subtabulation head.Outside a yielding indicating device (backoff indicator, BI) subtabulation head, each medium access is controlled subtabulation head and all corresponding to a medium access, is controlled arbitrary access response.Please refer to the 2nd figure, the 2nd figure is the schematic diagram that in the 1st figure, medium access is controlled the medium access control agreement subtabulation head of Protocol Data Unit.As shown in Figure 2, medium access control subtabulation head is comprised of three fields (E field/T field/RAPID field).Making a concession indicating device subtabulation head is comprised of five fields (E field/T field/R field/R field/BI field).E field represents an expansion field, the mark (flag) whether it has other gauge outfits to exist for indication medium access control gauge outfit.E field is set as " 1 ", in order to indication, have at least medium access to control subtabulation head or make a concession indicating device subtabulation head to exist.E field is set as " 0 ", in order to indicate medium access to control arbitrary access response, originate in next position.T field is a classification field, the mark whether it comprises the leading indicating device of an arbitrary access (Random Access Preamble Identifier, RAPID) or make a concession indicating device for indication medium access control subtabulation head.R field is a reservation position, is generally set as " 0 ".Make a concession indicator field and can differentiate the overload condition of cellular community.Making a concession indicator field length is four.RAPID field includes the leading indicating device of arbitrary access, can distinguish that the arbitrary access that in RAP, user side transmits is leading.The length of RAPID field is six.
Please refer to the 3rd figure, the 3rd figure is that a known medium access is controlled the schematic diagram that arbitrary access is responded.Medium access is controlled the length of arbitrary access response and is fixed, and medium access control arbitrary access response is comprised of following field.R field is a reservation position, is generally set as " 0 ".One shifts to an earlier date sequential (timingadvance, TA) instruction field, is used to refer to an index value TA (0-1282).Index value TA is used for controlling the sequential adjustment that user side is used.Sequential instruction field is seven in advance.One up link permits the indication of amount field for the resource of up link.It is 20 that up link permits the length of amount field.The one temporary cellular community temporary transient identifier field of Wi-Fi is used to refer to the temporary transient identification that user side is used during RAP.The length of the temporary transient identifier field of temporary cellular community Wi-Fi is 17.
As mentioned above, medium access is controlled use and the packet format that transmission is relevant to the temporary transient identifier in specific wireless networking.According to Long Term Evolution formula system specifications, when receiving by being relevant to the temporary transient identifier of cellular community Wi-Fi of user side and medium access that Wi-Fi temporary transient identifier in the cellular community of semi-persistent scheduling is identified, media storage control unit controls Protocol Data Unit (, the medium access that is mapped to exclusive traffic passage and exclusive control channel is controlled Protocol Data Unit) time, if medium access is controlled Protocol Data Unit, comprise improper value, media storage control unit abandons received medium access and controls Protocol Data Unit.Yet, current any packet error that there is no standard can process to be mapped to the medium access control Protocol Data Unit of shared control channel.
In addition, during RAP, when being relevant to medium access, controlling medium access that arbitrary access responds and control Protocol Data Unit when received, there is no at present medium access and control the related specifications that arbitrary access is responded.Therefore, if the medium access of a mistake is controlled arbitrary access, respond while being received, user side possibly cannot judge or ignore medium access and control the mistake that arbitrary access is responded.

Please refer to the 5th figure, the 5th figure is the schematic diagram of the embodiment of the present invention one communication device 50.Communication device 50 can be the mobile device in the 4th figure, and it comprises a processing unit 500, a storage element 510 and a communication interface unit 520.Processing unit 500 can be a microprocessor or an Application Specific Integrated Circuit (Application-Specific Integrated Circuit, ASIC).Storage element 510 can be arbitrary data memory device, and it is used for storing a procedure code 514, can see through processing unit 500 and read and carry out.For instance, storage element 510 can be user identification module (Subscriber Identity Module, SIM), read-only memory (Read-Only Memory, ROM), random access memory (Random-AccessMemory, RAM), compact disc read-only memory (CD-ROMs), tape (Magnetic Tapes), floppy disk (Floppy Disks), optical data storage device (Optical Data Storage Devices) etc., and be not limited to this.Communication control boundary element 520 can be a wireless transceiver, and its operation result according to processing unit 500 is used for carrying out wireless telecommunications with networking end.
Please refer to the 6th figure, the 6th figure is the schematic diagram of the embodiment of the present invention one flow process 60.Flow process 60, for a user side of a wireless telecommunication system, is used for processing packet error.Flow process 60 can be compiled into procedure code 514, and comprises the following step:
Step 600: start.
Step 610: receive a Protocol Data Unit (Protocol Data Unit, PDU).
Step 612: obtain a data payload from the Protocol Data Unit having received.
Step 614: according to a preset data payload format, check data Payload.
Step 616: finish.
According to flow process 60, after Protocol Data Unit is received, user side is therefrom obtained data payload.Then, user side check data Payload, to process packet error.The length that preset data payload format comprises data payload and number range etc.If assay designation data Payload is wrong, the embodiment of the present invention is taked corresponding action, to avoid the field value of user side application error, avoids by this program error to occur.
For instance, user side can see through an arbitrary access (Random Access, RA) program, receives arbitrary access and responds (Random Access Response, RAR) medium access of message is controlled (mediaaccess control, MAC) Protocol Data Unit.During RAP, for receiving media access control Protocol Data Unit, user side is according to the temporary transient identifier of an arbitrary access Wi-Fi (Random Access Radio Network Temporary Identifier, RA-RNTI) monitor an entity downlink paths (Physical Downlink Control Channel, PDCCH) and control Protocol Data Unit to detect medium access.The temporary transient identifier of arbitrary access Wi-Fi can identify user side and transmit time domain and the frequency domain resource that an arbitrary access leading (RA preamble) is used.Medium access is controlled Protocol Data Unit and is included a medium access control gauge outfit and medium access control data payload.Medium access is controlled gauge outfit and is included at least one medium access control subtabulation head.Data payload includes at least one medium access control arbitrary access response (MAC RAR) and selectivity is filled up (Padding) position.Except a yielding indicating device (backoff indicator, BI) outside subtabulation head, each subtabulation head includes the leading identifier of an arbitrary access (Random Access Preamble Identifier, and correspond to medium access in data payload and control arbitrary access and respond RAPID).After medium access control Protocol Data Unit is received, user side is controlled subtabulation head from medium access, find the leading identifier of the leading arbitrary access conforming to of arbitrary access transmitting with previous user side, and according to the leading identifier of the arbitrary access conforming to, obtain corresponding to the medium access of the leading identifier of arbitrary access conforming to control arbitrary access respond (in below, the medium access corresponding with the leading identifier of the arbitrary access conforming to control arbitrary access respond all with medium access, control arbitrary access and respond MAC RAR_1 and represent).
Afterwards, user side is according to preset data payload format, field in check medium access control arbitrary access response MAC RAR_1 (for example: one shifts to an earlier date sequential instruction (timing advance command) field, a up link fair amount (uplink grant) field and the temporary transient identifier of a temporary cellular community Wi-Fi (temporary cell radio network temporary identifier, the correctness of the data payload that temporaryC-RNTI) field), and by this judgement has received.Preset data payload format can be as shown in Figure 3.For instance, if medium access control arbitrary access respond MACRAR_1 sequential instruction hurdle value is not within the scope of 0-1282 in advance time, can be judged to be wrong.
When the vicious field value of above-mentioned either field tool, error format or error field length, it is wrong that user side judgement medium access is controlled arbitrary access response MAC RAR_1, and ignore medium access and control arbitrary access response MAC RAR_1, as never received medium access, control arbitrary access response MAC RAR_1.
If medium access is controlled Protocol Data Unit, have the arbitrary access of the medium access control over one response MAC RAR_1, user side is checked remaining medium access to control arbitrary access and is responded MACRAR_1, and repeats above-mentioned steps.If it is all wrong that assay indicates all medium access to control arbitrary access response MAC RAR_1, user side thinks that the medium access control Protocol Data Unit having received does not have the leading identifier of the arbitrary access conforming to, and lasting monitoring entity down link control channel, to detect another medium access of being identified by the temporary transient identifier of arbitrary access Wi-Fi, control Protocol Data Unit, in further during remaining arbitrary access form (RA window), obtain the medium access relevant to user side and control arbitrary access response.In other words, when also not having correct medium access control arbitrary access to respond in remaining arbitrary access form, user side continues to carry out follow-up RAP, and judges the failure that is received as of medium access control arbitrary access response.
In addition, if medium access is controlled Protocol Data Unit, comprise yielding indicating device subtabulation head, user side is set yielding indicating device accordingly.
Therefore, see through check medium access and control the field in arbitrary access response MAC RAR_1, whether user side can judge that MAC RAR_1 is responded in medium access control arbitrary access wrong.If it is wrong that MAC RAR_1 is responded in medium access control arbitrary access, user side is ignored medium access and is controlled arbitrary access response MAC RAR_1, treats as and never receives medium access control arbitrary access response MACRAR_1.When if the interior all arbitrary accesses response of medium access control Protocol Data Unit MACRAR_1 is all wrong, user side thinks that received medium access control Protocol Data Unit does not have the leading identifier of the arbitrary access conforming to, and continue to monitor entity down link control channel, to detect another medium access, control Protocol Data Unit.User side checks the medium access control arbitrary access response MAC RAR_1 in another medium access control Protocol Data Unit receiving again.Thus, the embodiment of the present invention provides user side to process medium access and controls the wrong method that arbitrary access is responded, and to avoid user side to apply mechanically medium access, controls the RAP mistake that in arbitrary access response, incorrect field value was caused.
Please refer to 7a figure and 7b figure, 7a figure and 7b figure are the schematic diagram of the embodiment of the present invention one flow process 70.Flow process 70, for a user side of a wireless telecommunication system, is used for processing a medium access and controls Protocol Data Unit mistake, and wherein medium access control Protocol Data Unit has the packet format shown in 1-3 figure.Flow process 70 can be compiled into procedure code 514, and comprises the following step:
Step 700: start.
Step 702: during a RAP, receive a medium access control Protocol Data Unit that includes a plurality of subtabulation heads and a plurality of medium access control arbitrary access response according to the temporary transient identifier of an arbitrary access Wi-Fi (RA-RNTI).
Step 704: the leading identifier of an arbitrary access and the E field of sequentially checking subtabulation head.
Step 706: judge leading the conforming to of arbitrary access that the leading identifier of arbitrary access had previously transmitted with user side? if so, perform step 708; If not, perform step 716.
Step 708: according to the leading identifier of the arbitrary access conforming to, obtain the medium access of a correspondence and control arbitrary access response MAC RAR_1.
Step 710: check medium access is controlled one of arbitrary access response MAC RAR_1 and shifted to an earlier date sequential instruction field, a up link fair amount field and the temporary transient identifier field of a temporary cellular community Wi-Fi.
Step 712: whether judgement in advance sequential instruction field, up link permits any one of amount field and the temporary transient identifier field of temporary cellular community Wi-Fi wrong? if so, perform step 714; If not, perform step 722.
Step 714: ignore medium access and control arbitrary access response MAC RAR_1 and judge that medium access is controlled arbitrary access response MAC RAR_1 never received.
Step 716: the field value that judges E field is " 0 "? if so, perform step 718; Perform step if not 704.
Step 718: judgement medium access protocol data cell does not have the leading identifier of the arbitrary access conforming to.
Step 720: continue monitoring entity down link control channel, and continue to carry out RAP.
Step 722: finish.
According to flow process 70, user side is sequentially checked the leading identifier of arbitrary access and E field, once find that there is correct medium access, controls arbitrary access response MAC RAR_1, ends check.E field is set as " 0 ", represent that it is last medium access control arbitrary access response that medium access is controlled Protocol Data Unit that the corresponding medium access control of this subtabulation head arbitrary access is responded.E field is set as " 1 ", presentation medium access control Protocol Data Unit also comprises the corresponding medium access of other subtabulation heads and controls arbitrary access response.At step 716-718, if user side is checked through last medium access, control arbitrary access response, and it is wrong to judge that last medium access is controlled arbitrary access response, user side abandons this medium access and controls Protocol Data Unit.In afterwards during arbitrary access form, user side detects another medium access and controls Protocol Data Unit in entity down link control channel, to obtain the medium access relevant to user side, controls arbitrary access response.Detect medium access control the mode of Protocol Data Unit be user side according to the Time And Frequency information of the temporary transient identifier of arbitrary access Wi-Fi, in arbitrary access form, on corresponding Time And Frequency, detect and whether have medium access to control Protocol Data Unit.The mode of operation that flow process 70 is detailed can, with reference to above, not repeat in this.
Certainly the embodiment of the present invention can adopt other alternative steps in flow process 70.For instance, user side is not ignored medium access and is controlled arbitrary access response, but the medium access that stops monitoring in down link control channel is controlled Protocol Data Unit, and announces that arbitrary access response message takes defeat.Then, user side continues to carry out follow-up RAP, to reselect the leading identifier of arbitrary access resource and arbitrary access.
Embodiment of the present invention flow process 60 is processed the mode of packet error can similarly control agreement unit for being mapped to a medium access that shares control channel (common control channel, CCCH).The medium access control agreement unit that shares control channel includes a gauge outfit and a data payload.Data payload includes a plurality of medium access and controls unit (MAC control element) and medium access control servo data unit (MAC Service Data Unit, MAC SDU).User side is according to the temporary transient identifier of a temporary cellular community Wi-Fi (Temporary C-RNTI), at the upper medium access that receives of a down link sharing channel (downlink Shared Channel, DL-SCH), control Protocol Data Unit.The temporary transient identifier of temporary cellular community Wi-Fi can see through entity down link control channel and be assigned to user side.User side is found the subtabulation head that logical channel identifier field value is " 00000 " (that is, sharing control channel), and according to this subtabulation head, obtains corresponding medium access and control unit or medium access control servo data unit.Then, user side according to user side and networking end default field length, field value scope jointly, check medium access controls unit or medium access is controlled servo data unit.If assay is failed, user side judges that medium access is controlled unit's control or medium access control servo data unit is wrong, and abandons the medium access control Protocol Data Unit having received.Therefore, user side can guarantee to be mapped to that to share the access control of the receiving media Protocol Data Unit of control channel correct, to avoid adopting the medium access that shares control channel to control data or set point wrong in Protocol Data Unit, and then avoid relative program mistake or failed situation to occur.
Medium access is controlled unit and be can be following any medium access and control unit: a buffer state reports medium access control unit,, the temporary transient identifier medium access of a cellular community Wi-Fi controls unit, a discontinuous reception (discontinuous reception, DRX) instruction media access control and controls unit, a user side competition and solve that (contention resolution) identification medium access is controlled unit, unit is controlled in a sequential instruction media access control in advance and a power headroom medium access is controlled unit.It is example that unit is controlled in the in advance sequential instruction media access control of take, sequential instruction media access control in advance control unit by a R field and in advance sequential instruction field formed.R field is the reservation position of two of length.Sequential instruction field is used for controlling the sequential adjustment that user side should be used in advance.The length of sequential instruction field is six in advance.Therefore, user side can be checked length and the field value that medium access is controlled first form, retained position and shift to an earlier date sequential instruction field.
